Flutter-pi stops here:

detected VideoCore IV as underlying graphics chip, and VC4 as the driver.
Reporting modified GL_EXTENSIONS string that doesn't contain non-working extensions.

Flutter version is matching engine-binaries (2.2.2 both). Also tried to run flutter-pi with sudo and got the same output.
Any advice to advance past this?

1. make sure no desktop environment (X.org, wayland) is running. Select boot into console in raspi-config (see the readme)
2. make sure no other instance of flutter-pi is running. It's possible flutter-pi is running even though you see the console on your display. To make sure no instance is running execute killall flutter-pi
